[0048] The embodiment of the present application provides a valve core, which includes a shell 100, a switching component 200, a static component 300 and a driving assembly 400.

[0049] The shell 100 forms a containing cavity, and a water inlet groove 500 is provided on the outer wall of the shell 100, and the water inlet groove 500 is communicated with the containing cavity. The switching member 200 is located in the containing cavity, and the switching member 200 is provided with a switching hole 210 running through it. The static member 300 is located in the containing cavity, and the static member 300 is provided with a plurality of water outlet holes 310 running through it, and the water outlet holes 310 are communicated with the outside of the shell 100. The driving component 400 can be rotatably mounted on the shell 100, and the driving component 400 is transmission-connected with the switching member 200. The driving component 400 is used to drive the switching member 200 to rotate, and when the switching hole 210 is located in the middle position of two adjacent water outlet holes 310, the switching hole 210 is at least partially communicated with the two adjacent water outlet holes 310.

[0050] See also Figure 1 , Figure 2 as well as Figure 3 As shown, the present application drives the switching member 200 to rotate relative to the stationary member 300 through the driving component 400, thereby changing the position between the switching hole 210 and each water outlet hole 310. During the rotation of the switching member 200, the switching hole 210 can be overlapped with different water outlet holes 310 to achieve communication, so that the water entering the switching hole 210 can flow out from the water outlet hole 310 connected thereto.

[0051] Please continue reading Figure 1 and Figure 2 As shown, water enters the switching hole 210 from the water inlet groove 500 , and the water flows out to the outside through the channel formed by the switching hole 210 and the water outlet hole 310 , thereby realizing the switching of water delivery to different switching hole 210 positions.

[0052] See also Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, in the initial state, the switching hole 210 is only connected to one of the water outlet holes 310 ( Figure 6 As shown in the figure, a plurality of shielding parts 320 are arranged on the surface of the stationary part 300 facing the switching part 200, and each shielding part 320 is located between two adjacent water outlet holes 310. When the switching part 200 rotates, the switching hole 210 gradually moves toward one of the shielding parts 320. When the switching hole 210 rotates to the position between the two adjacent water outlet holes 310, that is, when the position of the shielding part 320 coincides with the position of the switching hole 210, part of the switching hole 210 is simultaneously connected with the two adjacent water outlet holes 310 ( Figure 7 As shown), water flows continuously during the switching process, achieving smooth switching and improving user experience.

[0053] See also Figure 2 , Figure 5As shown, there is a gap between the switching member 200 and the inner wall of the accommodating chamber, and the shielding portion 320 is a groove connected to the circumferential surface of the static member 300, and the groove is connected to the gap between the switching member 200 and the inner wall of the accommodating chamber. When the switching hole 210 coincides with the shielding portion 320, the shielding portion 320 will not suddenly block the water from the switching hole 210. A small part of the water will be transported out through the channel connecting the switching hole 210 and the two water outlet holes 310, and the other part of the water will achieve pressure balance through the channel formed by the groove and the gap to prevent the shielding portion 320 from being given impact force.

[0054] Exemplarily, the number of water outlet holes 310 and shielding portion 320 are both three, and they are evenly distributed about the center of the stationary part 300. The size and shape of the water outlet holes 310 and the shielding portion 320 are not limited here. In this embodiment, the shape of the water outlet holes 310 and the shielding portion 320 is approximately fan-shaped.

[0055] The shell 100 includes a base 110 and an outer shell 120. The base 110 and the outer shell 120 are detachably connected. A through hole 111 is provided on the base 110 and passes through the base 110. The position of the through hole 111 is the same as that of the water outlet 310 and they are connected. The base 110 and the outer shell 120 define a receiving cavity, and the water inlet groove 500 is provided on the outer wall of the outer shell 120.

[0056] See also Figure 1 , Figure 2 as well as Figure 8 As shown, in order to facilitate the outflow of water entering the water outlet hole 310, a through hole 111 is opened on the bottom surface of the base 110, and the number and position of the through holes 111 are the same as the water outlet hole 310. The water outlet hole 310 is connected to the outside through the through hole 111. The shape of the through hole 111 can be the same as or different from the water outlet hole 310, as long as the water from the water outlet hole 310 can flow out.

[0057] Exemplarily, the number of the through holes 111 is three, and the shape of the through holes 111 is circular.

[0058] Furthermore, in order to prevent water leakage from occurring at the connection position between the water outlet hole 310 and the base 110 , a corresponding sealing ring may be provided at the connection position between the water outlet hole 310 and the base 110 to achieve sealing.

[0059] The shell 100 also includes a connecting structure 130, which includes a plurality of first positioning grooves 131 provided on the outer peripheral surface of the stationary part 300, a clamping block 132 and a second positioning block 134 provided on the outer peripheral surface of the base 110, a clamping groove 135 provided on the outer wall of the shell 120, a first positioning block 133 provided on the side of the second positioning block 134 close to the center direction of the shell 120, a second positioning groove 136 provided on the end surface of the shell 120 facing the base 110, the clamping block 132 passes through the first positioning groove 131 to be clamped to the clamping groove 135, and the first positioning block 133 passes through the first positioning groove 131.

[0060] See also Figure 3 As shown, the first positioning groove 131 is opened on the outer peripheral surface of the stationary part 300. There are multiple first positioning grooves 131, which are not limited here and can be designed according to actual needs. For example, there are three first positioning grooves 131, and there are two clamping blocks 132, which are evenly arranged about the center of the base 110. During assembly, the clamping block 132 will be inserted into the first positioning groove 131, and the stationary part 300 is positioned under the clamping action of the clamping block 132 and the first positioning groove 131, and the clamping block 132 will pass through the first positioning groove 131 to the position of the clamping groove 135. The clamping block 132 is clamped with the clamping groove 135 to achieve the connection between the base 110 and the shell 120. That is to say, the clamping block 132 can not only realize the position positioning of the stationary part 300 but also realize the connection between the base 110 and the shell 120.

[0061] In one embodiment, in order to make the connection between the base 110 and the housing 120 more stable, the second positioning block 134 on the peripheral surface of the base 110 will penetrate into the second positioning groove 136, so as to achieve the position fixation between the base 110 and the housing 120.

[0062] In one embodiment, a first positioning block 133 is provided on the inner side surface of one or all of the second positioning blocks 134. When the locking block 132 penetrates into the first positioning groove 131, the first positioning block 133 also penetrates into the first positioning groove 131 at other positions, thereby further realizing the positioning of the stationary part 300.

[0063] The area of ​​the switching hole 210 is greater than or equal to the area of ​​the water outlet hole 310. The switching hole 210 includes a water inlet portion 211, a first connecting portion 212 and a second connecting portion 213. The water inlet portion 211 penetrates the switching member 200 along a first direction. The first connecting portion 212 is opened on a side of the water inlet portion 211 close to the center direction of the switching member 200. The second connecting portion 213 is opened on a side of the water inlet portion 211 away from the center direction of the switching member 200.

[0064] See also Figure 4 As shown, the area of ​​the switching hole 210 should be larger than the area of ​​the water outlet hole 310 , so as to surround the entire water outlet hole 310 and allow sufficient water to enter the water outlet hole 310 through the switching hole 210 .

[0065] See also Figure 4 as well as Fig.13 As shown, in one embodiment, the three water outlet holes 310 can be marked as position a, position b and position c. In the initial state, the switching hole 210 is set to coincide with the water outlet hole 310 at position a. The switching hole 210 consists of a water inlet portion 211, a first connecting portion 212 and a second connecting portion 213. During the rotation process, in order to allow enough water to enter the water outlet hole 310 at position a, a second connecting portion 213 is provided on the side of the water inlet portion 211 away from the center position of the switching member 200, and the second connecting portion 213 is recessed along the rotation direction.

[0066] like Fig.13 As shown, during the rotation of the switching hole 210 from position a to position b, the second connecting portion 213 gradually connects with the water outlet hole 310 at position a, thereby ensuring that enough water enters the water outlet hole 310 at position a, and then as the switching member 200 continues to rotate, as shown in FIG. Figure 7 as well as Fig.13 As shown, when the switching hole 210 reaches the position of the blocking portion 320, the first connecting portion 212 is now partially connected to the water outlet hole 310 at position a and partially connected to the water outlet hole 310 at position b, that is, water will enter the water outlet hole 310 at position a and the water outlet hole 310 at position b, that is, there will be no water outage during the switching process, and as the switching member 200 continues to rotate, the switching hole 210 will gradually move to the water outlet hole 310 at position b, thereby completing the switching. When the switching hole 210 needs to be switched from position b to position c, the switching process is the same as above and will not be described in detail here.

[0067] See also Fig.13 As shown, in the present embodiment, when the switching hole 210 is rotated and switched from position a to position b, the area of ​​the water outlet hole 310 at position a connected with the switching hole 210 gradually becomes smaller, and the area of ​​the water outlet hole 310 at position b connected with the switching hole 210 gradually becomes larger. That is to say, the switching from position a to position b is a gradual switching, and there will be no sudden disconnection of the water outlet hole 310 at position a and the switching hole 210, resulting in a sudden flow interruption, and there will be no sudden connection of the water outlet hole 310 at position b and the switching hole 210, resulting in a sudden water outflow. The disconnection and connection will be smoother during the entire switching process.

[0068] The driving assembly 400 includes a driving member 410, a transmission member 420 and a transmission structure 430. The driving member 410 is rotatably mounted on the shell 100, and the driving member 410 partially extends into the accommodating cavity. The transmission member 420 is arranged inside the accommodating cavity. The transmission member 420 is transmission-connected to the switching member 200. The transmission structure 430 is used for power transmission between the driving member 410 and the transmission member 420.

[0069] See also Figure 2 , Figure 3 As shown, in one embodiment, the driving member 410 is a shaft, and the transmission member 420 can be driven to rotate by screwing the driving member 410. Since the transmission member 420 and the switching member 200 are connected through the transmission structure 430, the rotational force from the driving member 410 can be applied to the switching member 200 through the transmission member 420, thereby driving the switching member 200 to rotate, and further realizing the switching connection between the switching hole 210 and each water outlet hole 310.

[0070] The driving member 410 includes a driving rod 411 . The outer circumference of the driving rod 411 is provided with at least one mounting groove 412 . A sealing member 413 is disposed in the mounting groove 412 . The driving rod 411 has a stepped surface, and a gasket 414 is disposed on the stepped surface.

[0071] See also Figure 2 , Figure 3 as well as Fig.12 As shown, the driving rod 411 is coaxial with the housing 120, and the housing 120 has an axial hole (not marked in the figure), which is connected to the accommodating cavity. The driving rod 411 is rotatably mounted on the axial hole, and part of it penetrates into the accommodating cavity and part of it is located outside the housing 120. In order to improve the sealing between the driving rod 411 and the axial hole, at least one mounting groove 412 is opened on the outer peripheral surface of the driving rod 411, and a sealing member 413 is installed in each mounting groove 412, and a gasket 414 is arranged on the step surface of the driving rod 411, and the gasket 414 is located between the step surface and the top wall of the accommodating cavity.

[0072] Exemplarily, the number of the mounting grooves 412 and the number of the sealing members 413 are both two, and the gasket 414 can be made of elastic materials such as rubber.

[0073] The transmission member 420 includes a follower 421, and a plurality of abutment blocks 422 are arranged on the end face of the follower 421 facing the switching member 200. A transmission block 423 is arranged on the edge of the abutment block 422 facing the switching member 200. A second transmission groove 700 is opened on the end face of the switching member 200 facing the follower 421, and the transmission block 423 extends deep into the second transmission groove 700.

[0074] See also Figure 2 , Figure 3 , Fig. 9 as well as Fig.10 As shown, the abutment block 422 abuts against the upper surface of the switching member 200, and the space formed between two adjacent abutment blocks 422 is connected to the water inlet groove 500. In order to be able to transmit the power on the driven member 421 to the switching member 200, the transmission block 423 penetrates into the second transmission groove 700 on the switching member 200. The transmission block 423 cooperates with the second transmission groove 700 to realize the clamping transmission, and each of the two side surfaces of the transmission block 423 is provided with a protrusion 424. After the transmission block 423 penetrates into the second transmission groove 700, the protrusion 424 abuts against the side wall of the second transmission groove 700, so that the power can be transmitted to the switching member 200 at the first time interval, preventing the existence of a gap between the transmission block 423 and the side wall of the second transmission groove 700.

[0075] In one embodiment, a cavity 425 is formed on the bottom surface of the abutment block 422 , and the production cost can be reduced to a certain extent by reducing the material consumption at the location of the cavity 425 .

[0076] Exemplarily, the number of the abutment blocks 422 and the number of the second transmission slots 700 are both three, and they are evenly spaced and distributed.

[0077] The transmission structure 430 includes a protrusion 432 arranged on the end surface of the driving member 410 facing the transmission member 420. The end surface of the transmission member 420 facing the driving member 410 is provided with a first transmission groove 431, and the protrusion 432 partially or completely penetrates into the first transmission groove 431.

[0078] See also Figure 2 , Figure 3 as well as Fig.10 As shown, the present application realizes the clamping transmission by penetrating the protrusion 432 on the bottom surface of the driving member 410 into the first transmission groove 431 on the upper surface of the transmission member 420 .

[0079] Exemplarily, the number of the first transmission groove 431 and the protrusion 432 can be designed according to actual needs. For example, when the shape of the protrusion 432 and the first transmission groove 431 is polygonal, such as a triangle, a quadrilateral, a pentagon, etc., the number of the first transmission groove 431 and the protrusion 432 can be only one or more. Specifically, when there is only one first transmission groove 431 and protrusion 432, the protrusion 432 can be set at the center position of the driving member 410, and the first transmission groove 431 is set at the center position of the transmission member 420. In this embodiment, the number of the first transmission groove 431 and the protrusion 432 can be one, two, three, etc.

[0080] A positioning structure 600 is provided in the transmission member 420, and the positioning structure 600 includes a receiving hole 610 opened on the circumferential surface of the transmission member 420, an elastic member 620 is provided in the receiving hole 610, and a connecting shaft 630 is also provided inside the receiving hole 610. A positioning member 640 is fixedly provided at the end of the connecting shaft 630 away from the center direction of the transmission member 420, and the positioning structure 600 also includes a limiting groove 650 provided on the inner wall of the receiving cavity.

[0081] See also Figure 2 , Fig. 9 , Fig.10 as well as Fig.11 As shown, in order to determine whether the switching hole 210 and the water outlet hole 310 coincide with each other during the rotation process, the positioning structure 600 is required to position the transmission member 420, thereby positioning the switching member 200. In this embodiment, there are multiple limit grooves 650, and the limit grooves 650 are opened on the inner wall of the base 110.

[0082] Exemplarily, the elastic member 620 is a compression spring.

[0083] Specifically, a receiving hole 610 is provided on the outer peripheral surface of the driven member 421, an elastic member 620 is placed in the receiving hole 610, and then the connecting shaft 630 is sleeved in the elastic member 620, at which time one end of the elastic member 620 abuts against the inner wall of the end of the receiving hole 610, and the other end of the elastic member 620 abuts against the outer wall of the positioning member 640. In the initial state, the positioning member 640 is inserted into one of the connecting shafts 630 to achieve position positioning. When the rotating driving member 410 is transmitted through the transmission member 420, the rotating driving member 410 is rotated. When the switching member 200 is driven to rotate, the driving member 410 rotates to overcome the elastic force of the elastic member 620 to make the positioning member 640 disengage from the limiting groove 650. Specifically, the positioning member 640 is subjected to the extrusion force so that the elastic member 620 contracts until the positioning member 640 disengages from the limiting groove 650. As the rotation continues, when the switching hole 210 coincides with one of the water outlet holes 310, the positioning member 640 re-enters the limiting groove 650 at the corresponding position under the action of the elastic force of the elastic member 620, and the position positioning is achieved.
